Andrea J Ibarra
Instructor, Anesthesiology, Perioperative and Pain Medicine
BioDr. Ibarra is a board-certified anesthesiologist with a focused research interest in preeclampsia and brain health. She completed her anesthesiology training at the University of Pittsburgh in 2019. Committed to bridging clinical excellence with rigorous scientific inquiry, Dr. Ibarra earned a master's degree in clinical research at Pitt. In 2023, her research promise was recognized with the prestigious SOAP-FAER Mentored Research Training Grant, which investigated the long-term neurological implications of preeclampsia. Her research portfolio centers on the intersection of anesthesia, women's health outcomes, and cognitive function, contributing to the growing body of evidence in perioperative neuroscience.
Outside of her clinical and academic pursuits, Dr. Ibarra is passionate about cooking and travel, drawing inspiration from diverse cultures around the world. -
Praveen Kalra
Clinical Associate Professor, Anesthesiology, Perioperative and Pain Medicine
BioDr. Praveen Kalra is Board Certified in Anesthesia and in Critical Care. He specializes in trauma, orthopedic, brain and spine surgery, urology, and cancer surgery. He was appointed Fellow of the American Society of Anesthesiology (FASA) in 2023. Appointed Medical Director of Sustainability for Stanford Healthcare in Dec 2023.
His professional interests include devising protocols for patient safety, informed consent, reducing the impact of anesthetics on the environment, addressing climate change by reducing green house gas emissions in the health care setting, resident education to emphasize evidence based safe care and mentoring medical students. He has been in practice for over 18 years.
Received the Inaugural Sustainability Ambassador Award in 2022 at SHC for removing Desflurane (anesthetic gas with highest global warming potential) from the OR and undertaking multiple initiatives such as creating a Green Team at SHC, an elective Green Rotation for residents, green curriculum video series and addressing plastic & biohazardous waste in the OR. Current projects are focused on decommissioning nitrous oxide pipelines in the OR. As Medical Director of Sustainability, I work on collaborating with experts, fostering clinician engagement in change management, and spearheading transformative initiatives.
Dr. Kalra completed his residency in Anesthesia from Harvard Medical School’s Beth Israel Deaconess Hospital and a fellowship in Critical Care from Johns Hopkins Hospital, Baltimore. -

Theodore Leng, MD, MS, FACS
Professor of Ophthalmology (Ophthalmology Research/Clinical Trials) and, by courtesy, of Anesthesiology, Perioperative and Pain Medicine (MSD)
Current Research and Scholarly InterestsDr. Leng was the first surgeon in California to perform a subretinal transplant of adult neural stem cells into patients with macular degeneration and is actively researching cell and gene regenerative therapies for macular degeneration, retinitis pigmentosa, Stargardt disease, and other degenerative conditions of the macula and retina. He also has an active program in imaging informatics, oculomics, and deep learning to identify patients who are at risk for eye and systemic disease. The end goal is earlier detection and rapid treatment to maximize outcomes.

M Bruce MacIver
Professor (Research) of Anesthesiology, Perioperative and Pain Medicine, Emeritus
Current Research and Scholarly InterestsWe study drug effects on the nervous system. Cellular, synaptic and molecular drug actions are investigated using electrophysiological and pharmacological tools in cortical/hippocampal brain slice preparations. We are also interested in mechanisms of neuronal integration and synchronization, especially related to patterns of EEG activity seen in vivo and in brain slices.

Edward R. Mariano, MD, MAS, FASA, FASRA
Professor of Anesthesiology, Perioperative and Pain Medicine (MSD)
On Partial Leave from 06/14/2026 To 08/22/2026Current Research and Scholarly InterestsMy clinical research interests include the development of techniques and patient care pathways to improve postoperative pain control and other surgical outcomes. I am particularly interested in using regional anesthesiology, the science and practice of modulating nerve transmission in the central neuraxis or within peripheral nerves, to produce target-specific and opioid-sparing pain relief and enhance recovery after surgery or injury.
